The invention relates to a device for punching out openwork patterns made of unburned ceramic materials, in which the stamps are displaceably mounted in guides. The invention further relates to a device for the sealing of a small device.

Devices of the aforementioned type have hitherto always been made of brass, the exact version between the stamps and the stamp guide which guides the stamps making the openings of the support plate or the counter ring very difficult to part, this ini.bE & snd £ ra therefore, Woil within a device nor & alerueice numerous Etejapol of the most important cross sections are often to be provided isit içtkrürjiteti Uarißlinien.

The invention is based on the principle of creating a device which is considerably easier to manufacture than that which is used for the specified purpose, and at the same time a method is to be specified by means of which this device can be obtained in the conventional way by Leisa.

InventionGensSB solves this task of redesigning a device by making Bowohl the temperature! FChrunç: s-plette eis that of the uJeikatuck tregande counter ring and the stamps made of plastic.

In an embodiment of the invention, this device is to be manufactured by a process in which the plaster cast of the parts to be cast from the new plastic is made, which are cast with a plastic coating, which is used to produce the mold for the parts of the parts .

The advantages achieved by the invention are not significant in terms of manufacturing technology: First of all Ιεεε, Εη the often very complicated cross-sectional shape of the stone plaster and the existing plasterboard reproduce very precisely, because the gypsum garbage is easy to process because of its low h * rtc . It should be noted here that the fend perforations in decorative porcelain do not lift somewhat gcometically elegant shapes, but rather, to increase the decorative shape, are provided with edges that appear curved or curved in a wide variety of shapes. FeldstveretFinally ir.uB at t the dimensioning of the plaster model for the stamp the spBters <r - U -

EchwindroeB of art coffee neglected usrdEn. Experience has shown that this does not cause any problems for model builders.

In the same quaint, the respective stamp places, the StESPpeirOhrungeplettB and the GegEnholterring are made with great form accuracy as a plaster model. Each of these plaster models is encased in a Ksutechukmaase and thus a GuSkille, which serves as a casting mold for the finished parts of the device. Practical tests have shown that the resilience of a device manufactured in the inventive UBIee bus plastic is used for punching out the ceramic masses of that binary device made of brass or a final material, if at all, if not essentially new.

A device according to the invention can only be produced at a fraction of the cost required for a brass part. Kstallteile existing are required. The much more cost-effective production of the Etenz tools new synthetic resin also allows more often a replacement of the tool parts that are no longer worn due to wear. This represents a further significant advantage compared to the previously existing tools, as reworking of the same tool leads to new edge skill, but leads to the earlier faults. Due to the high manufacturing costs of such a punching tool made of metal, it was necessary to varzichtat over time to the original PeBgenauigkelt! dsn, which led to deterioration in quality.

With the bub plastic device according to the invention, on the one hand the diversity of the openwork porcelain can be increased or reduced with application of the openwork device and on the other hand the accuracy of the openwork mouth can be increased or reduced with effort.

In the drawing, an exemplary embodiment of a device of the type improved here is shown, on the basis of which the main learning of this device and its mode of operation are explained. Show it:

1 is a side view of a punching device in the closed position (working position),

Z likes the top view of the stencil device. Fig. 1,

Fig. 3 is a side view of the same Stsnzvarrrichtung in the gs open position and

Fig. Is a scaled riargestslltan vertical section through the tool in the çsâchlos-εεπεπ position gerc. Fig. 1.

Accordingly, on the base plate 1, the counter-holder ring 2 is easily exchangeable via the SS pillars 3. As can be seen in 3bEsond & -ra, Fig. 3, both in the counter ring 2 and you in the stamp guide plate B 9, the same level is worked in, as are the corresponding openings, which in turn correspond to gEnBU dsm mu - * eter that are punched into the edge of the plate 5 eoII.

This edge ovation is punched out by means of the stamp 6, which are fastened in groups to the stamp plate 7 and which pass through the openings 8 of the stamp guide plate 9 after the reaming relief k of the plate 5 has been removed. ' This state is shown in Fig. K in an enlarged tfeßstebe.

I The stamp plates 7 are snittBla the bolt 10 and the PrEs-J sEnetempel 13 attached.

After the punching process, the plate 5, as can be seen in FIG. 3, is lifted by means of the vertically displaceable plate 11 and the counter ring 2 BUE and then taken by hand so that a further plate can now be punched.

The operation of the described tool is carried out by means of a swivel lever 1Z.

The Segan holder ring Z, the stamp 6 and the stamp guide * plate 9, which form the actual tool, come out
